Michael,Volvos now have amber running lights front and rear. They have an additional side indicator though.
Yes , Basically we normally have a small indicator repeater mounted on the back end of the front wing (fender). We don't normally have "yellow" lights permanently on with our side lights or head lights. Although commercial vehicles do.
I prefer the red rear lights - it makes more sense after all! It gives the car more of a "spaceship" feel :-)
With the DeLorean most people change the rear red side marker for a yellow one, (as on the front), then re-wire them so that they both flash with the indicator ( turn signal). I had to do this re-wiring on Dusty because it had been quite finished by Woller- Hodeck, indeed it still had the original American style rear lights as well.
Not so - you can just earth the existing bulb onto the + side of the front indicator. Simple.
If you do this conversion , you will of course do away with you permanent yellow side markers,( unless you go in for some fancy relays) as there is not room for a double filament bulb in the holder.
